Scanning Tunneling Microscopy Perspective of Structures on Reduced SrTiO3 (001) Surfaces
Published online by Cambridge University Press: 15 February 2011
Abstract
Scanning tunneling microscopy has been used in ultra high vacuum to provide atomic scale structural information on reduced SrTiO3(001) surfaces. Our tunneling images exhibit row-like features with 12 Å and 20 Å periodicities on the reduced surface. A local 2×1 reconstruction was also revealed on some regions of the surface. The experimental results are discussed in terms of the different sublimation rates of surface constituents and formation of lamella structures of Srn+lTinO3n+l.
